From a purely technical stand point, as in flow, rhyme scheme and pure lyricalism, i agree.

However i feel the subjects and what 2pac said in his tracks much more that Eminem's tracks. I also like Pac's voice better.

For big, he has one of the sickest voice ever, and he had one of those heavy flow that just destroys a beat. His rhymes were good too considering he did most of his work in 1993-1997. Back then he was already dropping multisyllabic bars. Everybody does it today but back then it was not as common.

Don't get me wrong, i really like eminem, i just wishes he would abord serious subjects more often.
